Rowin LEF- 317A

By: Raymond Scott on 12 September 2020
I bought this pedal from Artist guitars some time ago, to work with my Ukuleles. I like to lower the lower frequencies in the 100/200hz range to reduce the thump from the piezo pick up. That works well. However, I have since bought a mandolin that has a single coil pick up that straight to the 40 watt amp just doesn't seem to happen. I have used the Rowin LEF- 317A as a boost, so all frequencies level, the volume control acts as a boost. I therefore have a pedal that works with uke and mandolin.
